Alamgir II (Urdu: عالمگير ثانی) (6 June 1699 – 29 November 1759) was the fifteenth Mughal Emperor of India, who reigned from 3 June 1754 to 29 November 1759. He was the son of Jahandar Shah. Born Aziz-ud-Din, the second son of Jahandar Shah, was raised to the throne by Imad-ul-Mulk after he deposed Ahmad Shah Bahadur in 1754. On ascending the throne, he took the title of Alamgir and tried to follow the approach of Aurangzeb (Alamgir I). At the time of his accession to throne he was an old man of 55 years. He had no experience of administration and warfare as he had spent most of his life in jail. He was a weak ruler, with all powers vested in the hand of his vizier, Ghazi-ud-Din Imad-ul-Mulk. In 1756, Ahmad Shah Abdali invaded India once again and captured Delhi and plundered Mathura. Marathas became more powerful because of their collaboration with Imad-ul-Mulk, and dominated the whole of northern India. This was the peak of Maratha expansion, which caused great trouble for the Mughal Empire, already weak with no strong ruler. Relations between Alamgir II and his usurping vizier, Imad-ul-Mulk had now deteriorated. He was murdered by Imad-ul-Mulk. Alamgir II's son Ali Gauhar escaped persecution from Delhi, while Shah Jahan III was placed on the throne.
